WINDOW.

SPECIFICATION forming part of Letters Patent No. 620,515, dated February 28, 1899.

Application filed March 14, 1898. Serial No, 673,744- (No model.)

To (oZZ whom it may concern.-

Be it known that I, THOMAS S. TRIPP, a citizen of the United States, residing at Walton, in the county of Delaware, in the State of New York, have invented a certain-new and useful Improvement in Windows, of which the following is a specification.

The improvement is intended more particularly for shallow windows in basements and cellars, and I will describe it as thus applied.

I provide a rectangular frame or casing of proper size, flared both outwardly and inwardly, and mount the means for closing the window near the mid-thickness of such frame. The closing means are of three kinds-strong bars of iron or steel extending across the aperture in the mid-thickness, a window carrying glass and turning on an axis at the upper edge, and a removable screen, of wire-cloth or analogous material, applied on the exterior with provisions for easily engaging and removing it.

I have devised important improvements in the details.

The accompanying drawings form a part of this specification and represent what I consider the best means of carrying out the invention.

Figure 1 is a side elevation of my improved window with a section of the adjacent portion of a cellar-wall. Fig. 2 is a corresponding vertical section on the line 2 2 in Fig. 3. Fig. 2 is a section corresponding to Fig. 2, on a larger scale, and showing the sash in the open position. Fig. 3 is a face view from the outside, and Fig. 4 a face view from the inside. Fig. 5 is a corresponding view of a portion, showing a modification.

Similar letters of reference indicate corresponding parts in all the figures where they appear.

A is a rectangular casing of cast-iron in a single piece, A being the outward flare and A the inward flare. The form gives great strength with a small amount of metal and also takes hold very securely of the masonry or other material of the wall W.

A and A are sufficiently stout bars of iron or steel, set firmly in the frame-casting.

The entire window-frame'may be of cast iron or steel in one or more pieces.

In the inner flare A at the upper portion on each side, are formed pockets a, each adapted to receive and hold atrunnion B of the swinging frame or sash B. (See Fig. 4.) The sash is formed integrally of cast-iron, the inner edge being square and the outer edge being beveled uniformly outward on the face which is presented toward the exterior of the building, making the section apparently that of a right-angle triangle; but the opposite face is hollowed so as to approximately correspond. In the lower portion, at each side, is a pocket a, adapted to receive the locking-levers D, which are pivoted on the sash B at d. These levers are bent, as shown. The upper portions or arms D have sufficient weight to hold their respective levers by gravity in the opened or closed position when these arms are swung respectively inward or outward beyond the vertical line through their respective centers d. The lower arms D are thin and engage snugly in the correspondingly thin pockets at when it is re quired to hold the window closed.

A cross-bar B is formed integrally with the body B of the sash, the back face being plane and the front beveled, but of less depth than the main body. The lower portion of this is thicker and forms a boss, in which is bored a hole b, through which plays a horizontal slide 1, having a head I, carrying a washer 1 which receives the force of a helical spring J, abutting against the cross-bar B and having a sufficient head I at the other end for retaining the slide. WVhen the sash is dropped from the open position into the closed, the head I strikes a lug A provided on the frame A, and reduces the concussion. This slide and spring perform another function. The spring resists the last portion of the closing movement and requires to be overcome by a considerable force. When the sash has been thus forcibly closed and the lower arms D of the locking-levers are properly engaged in the pockets a, the spring maintains a sufficient pressure, such force tending to open thesash and avoids any looseness and rattling under any conditions. The force thus induced is also of advantage in preventing the lockinglevers D from being turned into the open position by chance.

Cement is used under the glass and wedges E, which may be simply of wood, are used between the bars B and B and the glass, said bars being cast in the bosses B and B, the glass being inserted from the top and resting on two small projections B B on the bottom of the sash.

I provide two or more holes a a one above the other, in the back fiare A at the center of the top.

K is a sliding bolt carried in the sash at the top and capable of sliding outward and inward, driven outward by a coiled spring L. I attach a chain H, leading down from such bolt and loosely secured at the lower edge,

By pulling the chain H the bolt is drawn inward, and after the sash has been raised fully or part way, as preferred in any case, the chain is slackened and the bolt K, thrust outward by the spring L, engages in the proper hole a or a and holds the sash up.

M is a frame applying from the outside, its central opening being a little shorter than that inv the inner frame or sash B, thus affording space for a gravity-hook N on each side, pivoted in the frame M and adapted to engage over the stout cross-bar A and hold the device in position. Each of the lockinghooks N has an arm N reaching outward, by which it may be operated from the outside.

The inner face of the frame M, the edges of which apply against the corresponding surface in the front flare A, may be plane. The opposite outer face is hollowed in cross-section, as indicated by m, and receives corresponding bars Q confined by screws R tapped into the frame lWI. A screen P, of sufficiently fine wire-cloth, is stretched across this frame, having holes previously formed for the several screws R and for the locking-hooks N. This screen is held by the pressure of the bars Q deflecting the corresponding portion of the cloth P into the hollows or grooves m. This construction allows of easy attachment of the wire-cloth, and the action of the bars Q in sinkinggentlyinto the corresponding grooves by the gradual tightening of the several screws R gently strains the wire-cloth, so that it is held in the required plane and taut condition. The material of the other part may be changed within wide limits.

Modifications may be made without departing from the principle or sacrificing the advantages of the invention. Instead of wirecloth the screen may be perforated metal. Parts of the invention can be used without the whole. The hooks N may be formed without the arms N, in which case the removal of the screen will require simply two persons, one inside to lift the locks and another outside to receive and remove the screen. The spaces for the wall between the flares A and A may have the cross-section more nearlypivot. Fig. 5 shows such form. Both have the gravity urging them into engagement in the apertures ct.

I claim as my invention- 1.- In a window the metal frame A having the cross-bars A A and provided with the' pockets a, a swinging sash journaled in said pockets, and bolt devices arranged to engage with other openings in the frame to hold the sash in an open position, substantially as herein specified.
